Sorption incineration of chlorinated hydrocarbons, acid, heavy metals, and excess nutrients in water using cool-derived solids

Students supported: 1 Undergrad, 2 Masters, 2 Ph.D.The basic objective of the research was the development of systems for the sorption and incineration of water pollutants based upon solid phases derived from coal. The research was designed within the context of an overall system that should provide a net gain of energy and that should be cost-effective because of the sale of energy and byproducts. The byproducts are obtained from the pyrolysis or gasification of coal. Some of the major objectives of the research were the following: (1) Production of char from coal in a manner maximizing valuable byproduct recovery, (2) development of the most effective and energy-conserving modes of char activation, (3) evaluation of coal chars for the absorption of contaminants from water, (4) determination of the effectiveness of ash from char incineration as a water purification additive, (5) evaluation of the incineration of the spent char for energy production and destruction or immobilization of sorbed water contaminants.Project # B-150-M

Characterization, renovation, and utilization of water from slurry transport systems

The transportation of a number of commodities as water slurries in pipelines offers a number of advantages which will make this method of transport more popular in coming years. Among the formeost of these advantages are high reliability, low operating costs, minimum environmental disruption, and ability to operate with nonpetroleum energy resources. Although coal is the most frequently mentioned material that is a candidate for slurry transport, other commodities including minerals, wood chips, and even solid refuse may be moved in this manner. Water used as a slurry transport medium must be properly characterized, renovated, and used in order to make slurry transport environmentally and economically acceptable.Project # B-145-MO Agreement # 14-34-0001-121

Some Unique Approaches to the Chromatographic and Spectrophotometric Analysis of Underground Coal Gasification By-product Waters and Their Applications to Environmental Control

Of the contaminants produced, by gasification, phenols are among the most likely to cause problems because of their abundance, water solubility, and environmental effects. Among the techniques employed are solvent extraction, ultraviolet spectrometric analysis, gas chromatography, and high performance liquid chromatography
